Outline of Final Research Achievements

In this study, we showed bacterial wilt and Verticillium wilt diseases of eggplants were suppressed by pre-inoculation with phenotype conversion (PC) mutants of Ralstonia solanacearum. As a result of investigating the optimal inoculation method of PC mutants for two diseases control, the shorter the period from inoculation of PC mutants to infection with pathogens, the higher control effect was obtained for both diseases. Furthermore, we showed the resistant cultivar (Solanum torvum cv. Tonashimu) with high control effect by PC strains. We demonstrated that inoculation of PC mutant with the seedlings that were grafted the resistant rootstock were effectively control against bacterial wilt and Verticillium wilt diseases.
